Stuttering has been associated with a range of anxiety disorders, including social phobia. In the general community, anxiety disorders are frequently associated with increased rates of mood and substance use disorders. Therefore, in the present study, the authors sought to determine the rate of mood and substance use disorders among adults who stutter.
The study employed a matched case-control design. Participants included 92 adults seeking treatment for stuttering and 920 age- and gender-matched controls. Mental health assessments were conducted via a computerized psychiatric diagnostic interview. Conditional logistic regression models were used to estimate odds ratios for the prevalence of mood and substance use disorders in both groups.
When compared with matched controls, adults seeking treatment for stuttering had twofold increased odds of meeting criteria for a 12-month diagnosis of any mood disorder but were not found to report significantly higher lifetime prevalence rates for any substance use disorder.
Although adults who stutter in the present study were characterized by significantly higher rates of mood disorders than matched controls, they do not appear to self-medicate with substances such as alcohol. Results are discussed in terms of treatment implications and possible reasons why adults who stutter may avoid alcohol.
口吃与一系列焦虑障碍有关，包括社交恐惧症。在普通人群中，焦虑障碍常与情绪障碍和物质使用障碍的发生率增加有关。因此，在本研究中，作者试图确定口吃成年人中情绪和物质使用障碍的发生率。
该研究采用了匹配病例对照设计。参与者包括 92 名寻求口吃治疗的成年人和 920 名年龄和性别匹配的对照者。通过计算机化的精神病学诊断访谈进行心理健康评估。使用条件逻辑回归模型估计两组中情绪和物质使用障碍的患病率的优势比。
与匹配的对照组相比，寻求口吃治疗的成年人出现任何心境障碍 12 个月诊断标准的可能性增加了一倍，但并未发现报告任何物质使用障碍的终生患病率显著升高。
尽管本研究中的口吃成年人的心境障碍发生率明显高于匹配的对照组，但他们似乎没有用酒精等物质自我治疗。结果从治疗意义和口吃成年人可能避免饮酒的可能原因方面进行了讨论。
